Quote

He sought a way to preserve the past. John Hershel was one of the founders of a new form of time travel.... a means to capture light and memories. He actually coined a word for it... photography. When you think about it, photography is a form of time travel. This man is staring at us from across the centuries, a ghost preserved by light.

The illegality of cannabis is outrageous.

I'd like the [Cosmos] series to be so visually stimulating that somebody who isn't even interested in the concepts will just watch for the effects. And I'd like people who are prepared to do some thinking to be really stimulated.

The difference between physics and metaphysics is not that the practitioners of one are smarter than the practitioners of the other. The difference is that the metaphysicist has no laboratory.
Carl Sagan
Image
The Apollo pictures of the whole Earth conveyed to multitudes something well known to astronomers: On the scale of the worlds - to say nothing of stars or galaxies - humans are inconsequential, a thin film of life on an obscure and solitary lump of rock and metal

We are like butterflies who flutter for a day and think it is forever.
Carl Sagan

It is clear that the nations of the world now can only rise and fall together. It is not a question of one nation winning at the expense of another. We must all help one another or all perish together.
Carl Sagan
Image
The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.

In Mozambique, the story goes, monkeys do not talk, because they know if they utter even a single word some man will come and put them to work.

You could just as well say that an agnostic is a deeply religious person with at least a rudimentary knowledge of human fallibility.
Carl Sagan

We live in an in-between universe where things change all right...but according to patterns, rules, or as we call them, laws of nature.
Carl Sagan
Image
We are, in the most profound sense, children of the Cosmos.
Carl Sagan

It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science.
Carl Sagan

If we say that God has always been, why not save a step and conclude that the universe has always been?
Carl Sagan
Image
But I try not to think with my gut. If I'm serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble.

Arguments from authority carry little weight – authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities at most, there are experts.
Carl Sagan

That we can now think of no mechanism for astrology is relevant but unconvincing. No mechanism was known, for example, for continental drift when it was proposed by Wegener. Nevertheless, we see that Wegener was right, and those who objected on the grounds of unavailable mechanism were wrong.

In more than one respect, the exploring of the Solar System and homesteading other worlds constitutes the beginning, much more than the end, of history.

The universe seems neither benign nor hostile, merely indifferent.
Carl Sagan

By exploring other worlds we safeguard this one. By itself, I think this fact more than justifies the money our species has spent in sending ships to other worlds. It is our fate to live during one of the most perilous and, at the same time, one of the most hopeful chapters in human history.

There is much that science doesn't understand, many mysteries still to be resolved. In a Universe tens of billions of light-years across and some ten or fifteen billion years old, this may be the case forever. We are constantly stumbling on new surprises
